lwm (Lightweight Window Manager) is a window manager for X that tries to keep out of your face. There are no icons, no button bars, no icon docks, no root menus, no nothing: if you want all that, then other programs can provide it.

There's no configurability either: if you want that, you want a different window manager; one that helps your operating system in its evil conquest of your disc space and its annexation of your physical memory.
